Proper attic ventilation results in energy savings from 5% up to 15% or more.Did you know?The average family of four generates 2 to 4 gallons of water vapor a day through activities such as cooking, cleaning, showering, laundry, and breathing. Some of this water vapor rises into your attic. Ventilation helps remove it before it causes problems such as wood rot, wet insulation, mold and mildew.Source: Moisture Control in Buildings, Heinz R.

Each home or building requires ventilation and selecting the right ventilation is the matter or proper research, knowledge of application, balancing the system and proper installation are all important factors. Consider some of the following types of products. ShingleVent® IIShingleVent II ridge vent installs on the peak of the roof allowing exhaust ventilation all along the roofline — end-to-end.This product proves that outstanding beauty and performance can be combined. Design features include an external baffle and internal weather filter for optimum airflow and weather protection. Less than an inch in height, this molded, high-impact copolymer shingle-over ridge vent permits capping of the ridge with shingles like the rest of the roof.The Edge™ VentAir Vent’s new The Edge™ Vent provides proper intake ventilation for homes with little or no overhang. It’s a roof-top installed, shingle-over intake vent designed based on roofing contractor feedback from our Ask the Expert™ seminars. It can be used to supplement existing soffit or undereave vents as well. The vent provides 9 square inches of net free area per linear foot.Roof-Mounted Power Attic VentElectric-powered attic vents use a thermostat and humidistat control to monitor heat and moisture buildup inside the attic.Featuring a low-profile dome, the power attic vent is unobtrusive when installed on the roof slanting away from the front of your home. It’s an efficient option to replace wind turbines or roof pots already in place. Direct-Drive Whole-House FansWhole-house fans are installed in a central hallway inside the house and pull fresh outdoor air through open windows. They are often used to augment air conditioning or instead of air conditioning in mild summertime climates.Direct drive whole-house fans are easy to install since no attic joists need to be cut. They feature a pull chain for easy operation.jThose are great products and they all serve unique applications and many work together, there are dozens more ventilation products but I have chosen to feature some of the most common and best types of products.
